Hi. New to this forum.

I was hiking today in an area I am very familiar with
and noticed a
disturbing problem with my garmin 60CSx. It was displaying my
position
way off on the map. I used a street as reference, which it showed me
just passed the street, yet I was at a position in the trail easily
500-800 feet
away from the street. It was about 21 degrees Fahrenheit,
which is within its
working specs.

This is disturbing because now I cannot trust the GPS with my
location
if I am in an unfamiliar or unknown location. Has this happened to
anyone before?

I have lock on street off in the map settings. After I got
to the car
and started driving home, after a mile or so it regained its correct
location.

Anyone experienced this before? Any solutions, advice?

Thanks!
Tony

Had it happen with an old Magellan 2000, when it told me I was several
hundred miles away from where I knew I was. Fortunately I _did_ know
where I was... :)

What kind of terrain? If it couldn't get a good signal, it should
display a message about "poor sattellite geometry" or some such, and
additionally the gps will tell you its estimated accuracy. Did you
happen to check that? Also in mountainous terrain or areas with tall
buildings, I'm told you can get errors from multipath reflections,
though I've never actually seen it.

Problems of that sort are usually related to bad map data.

To how many feet did it say it was accurate on the Satellite Page?

Also, if WAAS is off, turn it on. (And if it's on, try it off.)

I don't know the particular model, but some models have the facility to
change the coordinate referencing system. Might be worth a check to
ensure that the GPS and the map is using the same coordinates.
